If playing Volibear leader and then playing Set (a 4 Might unit that buffs itself to 5 Might), does Volibear's ability trigger to ramp?

Ruling: No, Volibear does not trigger to ramp when Set is played. Volibear sees Set enter as a 4 Might unit before Set's buff applies.

Sequence:

• Set is played as a 4 Might unit
• Volibear's ability checks and sees a 4 Might unit (does not trigger)
• Set's buff then applies, making it 5 Might

Nuances:

• The result would be different if Set entered already buffed, but since the buff is a play trigger, it happens after Volibear checks the unit's Might value
